BICYCLE-TIRE MACHINE.

SPECIFICATION forming part of Letters B a'tent No. 367,721. dated August2, l857.

Application filed November 26, 1856. Serial No. 219,990. (No model.)

To all whom it 17mg concern:

Be it known that l, VILLIAM A. MCCOOL, a citizen of the United States,residing at Perrysville, Ashland county, State of Ohio, have invented anew and useful Improvement in Bicycle-Tire Machines, of which thefollowing is a specication.

The object of my invention is to provide a machine in which strips ofmetal are properly bent and formed into tires over a revolving drum orwheel made of the desired size to correspond to the wheel actually usedin the bicycle, and adapted to have said drum replaced by other drums ofvarying sizes, so that one machine is capable of producing any sizedbicycle-tires that may be desired. One means of accomplishing thisresult is shown in the accompanying drawings, in which*A Figure lrepresents a side view of the 1na chine, the part of the revolving drumwhich penetrates below the floor not being shown.

Fig. 2 is a top plan.

Similar letters indicate similar parts in both of the iigures.

A is the frame of the machine.

B is the revolving wheel or drum.

G represents the pulleys for driving the machine connected by beltingwith the source of power. (Not shown.) These pulleys are mounted on theshaft a, the outer end of which is journaled in the grooved arm b andthe inner end of which is journaled in the framework.

Upon the shaft a is the pinion c, which gears with the gear-wheel D,mounted upon the shaft d, journaled in the frame-work aud carrying thebeveled gear e, which in turn engages the beveled gear E, which ismounted upon the main shaft of the machine, f. This main shaft fismounted in journal-boxes g y upon the frame of the machine, and carriesupon its outer end the drum or wheel B, before mentioned. On the shaft fis a set of pulleys, G, connected by belts with a corresponding set ofpulleys, H, upon secondary shaft l1., mounted in journal-boxes i z',secured to the framework of themachine. On the outer end ot this shaft7L is the pulley l, connected by a belt toa pulley on the shifter J. Theobject of this shifter J is to move the entering-*die gradually acrossthe surface of the drum B, as hereinafter eX- plained.

Mounted loosely upon av shaft, 71 are the arms K K, which support theentering-die L, through which the rod is fed tothe drum, and which byits inclined surface j holds the rod firmly to Athe surface of the drumto make it take the shape of the drum, and therefore cling to the sameduring its revolution.

Auxiliary support to the die L is furnished by the arm M, pivoted at 7sto the rod N, the other end of which is pivoted to the frame. work at Z.

The slotted guide O is provided` for enabling this swinging support forthe die L, com posed of the arms K K, M, and N, to be raised or loweredto bring it into close contact with the differentsized drums employed.This slotted guide is a grocved piece rigidlysecured at its upper end tothe arm K, and provided with a long longitudinal slot moving upon a setscrew or pin, m, threaded into the framework of the machine; It isreadily seen that by loosening` the grip of this screw m the wholearrangement of the die, with its.

supporting-arms, may be lowered from the position shown in Fig. 1', fulllines, to that shown by dotted lines, wlere it is held by turning in thescrew; or it may be held at any intermediate division that is desired.

The plate l?, Fig.2, which holds the entering.- die, is constructed asfollows: Acentralislot, a,

runs nearly the whole width of this plate P,

and the platform o is mounted over this slot in such a way that when thepulley on the adj nster J revolves this platform is fed along over thisslot a away from the pulley. In one corner of this platform are the tworollers p, between which the rod is fed to the drum through the die qand back under the inclined surface j, above mentioned. form o, with thedie, rollers, and inclined surA face, has been fed through thefulllength of the slot n, the machine is stopped, the tires that havebeen formed are removed from the drum B, and the platform 0, Src., arethrown back to their starting-point by the handle and handwheel R.

The operation of the machine may be read ily understood, and is asfollows: The end of a long strip of metal capable of making a largenumber of tires is inserted between the rollers p andthe machine startedby the revolution of the pulleys C, which, acting through Vhen theplatand thereby the rotation of the druni draws the rest of the rod through the die and rollers and winds it around the surface of the drum.By the time the drum has made one revolution the shifter has so changedthe position of the entering rollers and die, with their aecompanyingdevices, that the rod is fed alongside of the tire formed by the firstrevolution without overlapping. This is continued until the wholerodsurface of the drum is covered with tires, and the machine is thenstopped, the tires cut apart and removed from the drum, and the drumreplaced. lf desired, the drum,

with its encircling tires, may be removed and a new drum substituted, sothat the individual tires may bc removed and sprung into shape asconvenience permits.

l. The above-described bicycle-tire maehi ne provided with a revolving`drum for forming the tires, and an entering-die mounted on avertically-adjustable'support for conveying and shaping the tire to andabout said drum.

2. A bicycletire machine provided with a revolving druni capable offorming and holding a large number of tires, an entering-die and itssupporting-platform arranged on a Verticallyadjustable frame, and anadjuster arranged and adapted to move said platform and die graduallyacross the surface of said drum.

8. In a bicycle-tire machine, an adjustable support for holding theentering-die rollers and folding-edge, which consists of the arms M K K,rod N, and slotted arm O, arranged and adjusted substantially asdescribed, and for the purposes speciiied.
